You can leave the factory tweeters connected

 

whats a good speaker? i heard 2ohms is preffered...?

 

I'm not sure the factory radio can handle 2 ohms

 

ive heard it can.... need some confirmation on that one way or the other tho...

 

Crutchfield is saying if you have factory NAV and subwoofer this works (there is the option to delete this vehicle and change your year/model/factory radio to see what fits):
Car Selector
Infinity Reference X REF-8602cfx
Great for any power supply
You can power these speakers with up to 60 watts of RMS power — they'll work great with an external amplifier, but they're also sensitive enough to be a good match for a factory or aftermarket stereo. Plus, Infinity comes up with a safe way to get a little more power out of your system — these 3-ohm speakers combine with the speaker wire in your car so your car stereo sees actual 4-ohm impedance. ((True Four Ohm Impedance technology: speaker's 3-ohm impedance combines with speaker wire impedance for a 4-ohm load))Grilles are not included — factory grilles are appropriate for most installations.
Special $130 for first set $65 for the second
Double the speakers, not the price
Buy one pair of Infinity Reference X speakers or a component speaker set, and get a second, of equal or lesser value, for half price.

However they seem to be saying that they will not fit in the back, indicating that those are 5.25 speakers. Folks seemed to do fine with the 6x8 predecessor to this 6x8 Infininty, but also sounded like they had speakers in rear doors, not in the side panel next to the rear seat.

 

so they give us a discount on speakers we cant use. brilliant.

 

I'm a Polk guy. Their tweeters are amazing, I will get you some pics. Takes a little work with a pocket knife to install them, just make the factory tweeter hole 1" in diameter rather than the 7/8" that the factory tweets are.

The lower mid sound is not great which is why I'm also a kicker fan. I've got two 10" subs behind my seats!

 

I used these
Focal Access 570CA1 5"x7" 2-way car speakers at Crutchfield.com

 

GSRX,
Your speakers are no longer available haning been replaced by Focal Integration IC 570 at $249 per set.

 

Tux Scorpion:

I just pulled my side panel behind the rear seat. It is the same 6x8 speaker that is in the front doors. Unless the Infinity is way deeper, it should fit.

 

Yes, speaker size for all four locations is the same. 5x7 is the normal size, two way speakers fit.

I replaced all 4 of those and all four tweeters for about $250 using Polk db series. Lots of quality for the money.

 

actually they are replaced by these
Focal Access 570CA1 SG 5"x7" 2-way car speakers at Crutchfield.com
I really dont know the difference except they cost less
